A forward genetic approach to isolate Arabidopsis mutants altered in the regulation of the ALDH7B4 gene
(2016-09-30)The ALDH7B4 gene is a member of the ALDH super gene family which is known to be involved in stress tolerance, but the regulation of ALDHs was unknown. In the current studies, a forward genetic approach was used to propose ... -
Fossil record and new aspects of evolutionary history of Calcium biomineralization and plant waxes in fossil leaves
(2023-10-30)Calcium oxalate (CaOx) is one of the most common bio-minerals in extant plants. It plays a major role in a better understanding of plant taphonomy, environmental effects and evolution of calcium minerals in fossil plants. ... -
Fourier-Mukai transform for twisted sheaves
(2010-07-29)In this thesis we study Fourier-Mukai transforms between derived categories of twisted sheaves. We show that some well known results about the classification of surfaces under derived categories extend to the derived ... -
FOXO-abhängige Regulation von Immunabwehr und Lebensspanne in Drosophila melanogaster
(2013-05-22)Die Regulation der Lebensspanne durch den Insulinsignalweg (IlS) ist evolutionär konserviert und wird vor allem in C. elegans, Drosophila und der Maus untersucht. Es ist eine Reihe von Genen bekannt, die Bestandteile ... -
An FPGA-based Sampling ADC for the Crystal Barrel Calorimeter
(2019-12-09)The CBELSA/TAPS experiment in Bonn investigates the excitation spectra of protons and neutrons through meson-photoproduction. With its ability to polarize the target nucleons and the incident photon beam, the experiment ... -
FR900359, an inhibitor of guanine nucleotide dissociation, effectively blunts signaling of GTPase-deficient Gq: mechanism of action and relevance for treating Gq-driven cancers
(2019-08-01)Uveal melanoma (UM), the most common cancer of the adult eye, is known to have poor prognosis. Over 50% of patients are likely to develop metastasis. In more than 80% of the cases UM is driven by an activating mutation in ... -
Fragen des Wasserhaushalts im Mittelrheingebiet
(1947)Eine durchgearbeitete rheinische Hydrologie, wie sie der vorliegenden Untersuchung zuerst als Ziel vorgeschwebt hatte, kann nur in einer engen Zusammenarbeit mit den rheinischen Universitätsinstituten geschaffen werden, ... -
Frauenarbeitsmarkt und regionale Wirtschaftsstruktur: Ein Beitrag zur Geographischen Arbeitsmarktforschung - dargestellt am Beispiel der Städte Köln und Leverkusen -
(1994)Für die Geographie ist die "Arbeitsmarktforschung" ein junges Forschungsgebiet, dessen Wurzeln im anglo-amerikanischen Sprachraum liegen. Im deutschsprachigen Raum wurde dieser Forschungsbereich bis in die 70er Jahre ... -
Free Theorems in Languages with Real-World Programming Features
(2013-11-07)Free theorems, type-based assertions about functions, have become a prominent reasoning tool in functional programming languages. But their correct application requires a lot of care. Restrictions arise due to features ... -
Der Fremdenverkehr in den linksrheinischen Kleinstädten zwischen Bingen und Koblenz
(1971)Das Untersuchungsgebiet umfaßt die linksseitigen Kleinstädte des oberen Mittelrheintales Bacharch, Oberwesel, St. Goar und Boppard mit den verwaltungsmäßig zu ihnen gehörenden Rheinufer- und Rheinhunsrückdörfem.

Frequency Domain Methods in Recurrent Neural Networks for Sequential Data Processing
(2021-07-29)Machine learning algorithms now make it possible for computers to solve problems, which were thought to be impossible to automize. Neural Speech processing, convolutional neural networks, and other recent advances are ... -
From C-phosphanylated thiazole-2-thiones to phosphaalkenes and tricyclic 1,4-diphosphinines
(2019-05-15)The PhD Thesis “From C-phosphanylated thiazole-2-thiones to phosphaalkenes and tricyclic 1,4-diphosphinines” describes investigations on the synthesis of thiazolyl substituted phosphaalkenes, tricyclic 1,4-dihydro-1,4-di ... -
From Acoustic Mismatch Towards Blind Acoustic Model Selection in Automatic Speech Recognition
(2013-05-24)Acoustic distortion and acoustic mismatch are two of the most critical aspects influencing automatic speech recognition. A speech signal recorded from a speaker in a certain acoustic environment compared to a signal from ... -
From cell penetrating peptides to peptoids and polyamines as novel artificial molecular transporters: Entwicklung neuer Delivery-Strategien für siRNAs ; Von zellpenetrierenden Peptiden zu Peptoiden und Polyaminen als neuartige molekulare Transporter
(2005)In recent years, RNA interference has gained a lot of importance as a tool for posttranscriptional silencing of genes due to its high specificity, efficiency and ease of application. In mammalian cells RNAi is triggered ... -
From cell to robot: A bio-inspired locomotion device
(2014-05-02)Bionics or biomimetics is an interdisciplinary research field, a scientific approach to applicate naturally developed biological systems, methods and solutions to the study and design of technology and engineering systems. ... -
From Density Functional Theory to Tight Binding: Development of Robust and Efficient Quantum Chemistry Methods
(2022-12-07)The main topics of this thesis are efficient quantum chemical methods, their development, and the verification using existing and newly devised benchmark sets. The spectrum of quantum chemical methods discussed here includes ... -
From galaxies to the cosmic web and back: the interplay of different scales in galaxy formation and cosmic reionization
(2020-10-08)The evolution of the Universe is primarily governed by gravity, that triggers the development of a complex web-like distribution of galaxies. The latter are embedded in larger structures, called haloes, mainly composed by ... -
From glycosidase activity profiling to inhibitor discovery in the plant pathogen Pseudomonas syringae
(2018-05-25)Retaining glycosidases are important in plants for various biological processes. Plant genomes encode for more than 200 retaining glycosidases but the physiological roles and activities of many remain poorly understood. ... -
